OK I just got a 6 inch common pleco last week and when I put him in the tank he hid which I thought he would do. But he wont come out in the day time at all but when It is dark and I turn all the lights off he comes out but I'm worried because he wont eat at all in the day time every time I turn the lights on he goes crazy and finds the closest hiding spot he can and he takes plants out of the ground while he is doing that. I'm thinking he is stressed because of my 1 and a half foot long moray eel in the tank that killed my payara last week. His tankmates are 1 dinosaur bichir, 1 rtcxtsn hybrid catfish, 1 hujeta gar, 4 bala sharks, and 1 iredescent shark. Any help on this?
